PRESS-BUTTON.

To all whom "it may concern:

Be it known that I, RUDOLPH- sCI-IEEWE, a subject of the Emperor of Germany, residing at Hamburg, inGermany, have invented new and useful Improvements in Press-Buttons, of which the following is a specification.

This invention relates to a press button adapted to open automatically when its parts are turned to a certain position relatively to each other.

The invention can be carried out in such manner. that either the two parts of the button move relatively to each other, or that only one art of the button is movable relatively to t e other.

Several constructions of the press button according to this invention are illustrated, by way of example, in the accompanying drawings.

Figures 1 and .1 show in cross-section.

and plan the spring closing part. The same is constituted in the well. known manner by a disk (1 with pressed out hood, through the lateral slots of which springs 0 project into the interiorof the hood. In this construction the closing part is supposed to be secured to the dress material f by means of an eye 9. j

, According to the construction shown in cross-section and bottom view in Figs. 2 and 2, the closing part a is secured. to the fabric'or cloth f by means of points h pushed through the cloth and then bent over. The button part cooperates with the closing hood a in such manner that the button parts can be secured together when the button is inthe proper position, while when the button part isturned or moved,

the ress button is automatically opened.

Figs. 3 to 5 show various constructions of the button parts. The button 6 itselfis the same in all the constructions illustrated and comprises a truncated hollow cone provided near its bottom surface with pressed-in undercut portions d intended to receive the spring portions situated in the'interior of the hood of the closing part (1 The button 6 is preferably stamped-out of a disk (1 provided with a projection b for the purpose of facilitating its manipulation. The securililfg of the d1sk a to the fastenin eye z is e ected by flanging over the dis edge in such manner that the disk at and with it the Specification of Letters Patent.

button 0, could be turned. The securing of the eye 2'- to the fabric 7c is effected in well known manner by rolling in the eyeedge under pressure between the ring m and the disk n inserted into a cap Z. When the button e is introduced into the hood, the springs 0 spring into the undercut portions of the button when the latter is in the proper position, and firmly secure together the two parts of the button. If it is desired to unlock the button, then the button 0 must be turned by means of the handle I) in such manner that the springs c are disengaged from the recesses 03 and come to lie on the remaining smooth portion of the button cone. In that way. the springs are spread apart, and the pressure thus imparted to the springs is rendered inoperative by the two button parts separating from each other owingto the sliding of the s rings 0 on the button cone e, until the sprmgs 0 take up their normal position in the closing part.

In the constructions illustrated in Figs. 4 and 4, the button 6 is provided with aneye 0 which is passed through the securing eye 71 and rolled in with its end less stronglgpin the cap Z so that the button 6 can be turned by means of the projection b. The device for turning the button part in the event of press button closing devices being used in groups (as for loves, shoes, dress fasteners) can be arranged in such manner that all the buttons e can be turned by means of one string gzFconnecjting together all the projections 11 If? the construction illustrated in Fig. 5, the button part is practically identical with that shown in Fig. 4, onl in this case the button eye 0 is firml roll infinto the cap Z, and the turning of t e button e is effected by means of the cap I,

In the construction illustrated in Figs. 6

and 7, both button parts a and a are turnedv relatively to each other, for which purpose both parts are, provided with pro ections b b. Fig. 6 shows the two arts sewn on to the fabric and arranged si e by side, while Fig; 7 shows the two parts in the closing po sitlon. 'For the pur ose of opening the closing device it is mere y necessary to move the two arts in the direction of the arrow in v Fig. in order to make the button parts to separate automatically from eachother.

In the construction of the press button closing device shown in Fig. 8, the button 6 is rotatable on the disk a, as in the constructions shown in Figs. 4 and 5.

What I claim as my invention and desire to secure by Letters Patent is 1. In a pressure button, a conical male member having lateral recesses in the conical face thereof said conical face extending below said recesses, a female member and means within the latter for engaging said recesses and for causin the automatic se aration of the members iy the pressure 0 said means upon said conical face when the members are relatively rotated.

2. In a ressure button, a female portion, a truncated conical male portion having lateral recesses in the conical face thereof and oppositely acting resilient means within said female portion adapted to engage said recesses when the two portions are assembled and to be spread alpart upon the partial relaf t e sai tive rotation 0 portions, whereby the automatic separation of the latter is caused by the pressure of said means on said conical portion.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
